SPECIFICATION forming part of LettersPatent No. 739,991, dated September 29, 1903.

Application filed January 3,1903. Serial No. 137,685. (No model.)

T0 at whom it may concern:

Be it known that 1,. GEORGE HOWLETT DAVIS, a citizen of the United States, residing at Llewellyn Park,West Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Securing End Caps and J ournal-Pins to Music Rolls or Spools; and I do hereby declare the following to be'a'full, clear, and exact description of the invention, such as will enable others skilled 1 in the art .to which it appertains to make and use the same.

My present invention relates to a machine for securing the heads and journal -'pinsto the ends of spools forperforated music-sheets such as used in connection with self-playing musical instruments; and it has for its object to provide a machine of this character that will at once be simple in construction, easy of operation, and cheap to manufacture.

As is well known'in the art, perforated music-sheets for self-playin g musical instruments are usually wound. upon a'spool having end caps or heads and journal-pins,which j ournalpins serve topermit the spools to be removably inserted in socket-bearings in the self-playing instrument. Heretofore and prior to this invention it has been the custom to first nail the end caps or heads upon the ends of the spool proper and then drive in the j ournal-pins, these operations being performed separatelyby hand.

It is the purpose of this invention to provide a'machine that will simultaneously force or press thenails that secure the end caps or flanges and the journal-pins in position upon 'the ends. of the spool without liability of splitting the said caps; which is an objection present in the'hand-nailingoperation as heretofore practiced.

Briefly and generally. stated, the machine. comprises a supporting and centering device for the spool, 'a plunger having a driving:

head constructed to engage and press'the nails throughthe end cap into the end of the spool and to simultaneously force a journalpin in place, and means, such as a foot-treadle or other similar device, for operating the plunger.

In order to enable others to understand, make, and use my said invention, I will now proceed to describe the same in detail, referenee being had for this purpose to the accompanying drawings, in which--v Figure 1 is a side elevation, partly in section, of a machine constructed according to this invention. Fig. 2 is a front elevation, partly in section, showing a spool in position in the machine, the nails and journal-pin "the base 2 is a standard 3, having a forwardly-projectiug portion 4, to the end of which is pivoted at 5 a power-lever 6, having upon its under side a working face or cam 7 To thefree end of the lever 6 is pivoted a rod 8, which extends. down through an opening in the table and having its lower end linked to a foot-treadle 9, one end of which is pivoted to a suitable support 10. Arranged to move Vertically in suitable bearings in the standard 3 isa plunger 12, having a socket in its lower end into which is removably inserted a driving-head 13, said head having an opening 14 to" receive the projecting end of the journal-pin to be driven in the spool and a fiat driving face :or rim 15- to engage the nails. The said driving-head 13 is secured in position in the plunger by means of a set-screw 16. held elevated by means of springs 17 ,-having their opposite ends attached to projections 18 and 19 on the standard and plunger, respectively. The projections 19 onthe plunger are carried by a collar 20, adjustably secured to the plunger 12 by means of a set-screw 21. l The base 2 of the machine -frame is provided at its front portion, directly below the driving-head 13, with a cut out portion or open slot 22 to receive one end of the musicroll23 during the driving or forcing operation. 'Bolted to the under side of the table 1 is a 'U-shaped bracket 24, having in the horizontal portion 25 thereof an opening 26, which The plunger 12 is normally opening is in true vertical alinement with the opening 14 in the driving -head 13. The opening 26 in the horizontal portion 25 of the U-shaped bracket 2a is adapted to receive in a removable manner a centeringpin 27,

said pin being held in position by means of set-screw 28. The purpose of this pin will be presently explained. The U-shaped bracket 2i is preferably braced by means of arms 29, secured to the sides of the bracket and the bottom of the table, respectively.

The music-spool comprises a roll proper, 23, having at its opposite ends tenons 30, over which fit the end caps orheads 31,said caps being provided'with suitable openings to receive the tenons 30. Extending through each tenon 30 and for a short distance into the end of the roll 23 is a bore 32, adapted to receive the journal-pins 33, it being understood that there is a cap and a journal-pin secured to each end of the roll, the said caps being secured or fastened in position upon the ends of the roll by means of nails 34.

The operation of the machine is briefly as follows: Let it be assumed that an end cap 31 has been applied to one end of a roll 23 and that a journal-pin and nails 34 have been placed in position to be forced home, as shown in Fig. 5. The spool in this condition, with an end cap fitted to one end thereof only, is placed in the machine so that the journal pin and nails will lie directly below the driving -head 13 and the opening 2 in the tenon 30 at the lower end of the spool placed over the centering-pin 27, carried by the bracket 2%. By depressing the treadle 9 it will be seen that the plunger will be forced down, bringing the driving-head 13 into contact with the nails 2i and with the journalpin 33, forcing them home at one and the same time. During this operation it will be seen that the spool 23 is centered and held in true alinement by means of the centeringpin 27, the slot 22, and the opening 1& in the driving-head. Consequently the journal-pin and nails will be forced into place with accuracy. After applying end caps to one end of a number of spools the centering-pin 27 is removed, leaving the opening 26 free to receive the journal-pins 33 that have been thus inserted in the spools to act as centering means when the other end caps are being applied.

I do not wish to be understood as limiting myself to the precise details of construction herein shown and described, as various changes may be made without departing from the spirit of the invention.

Having thus described my invention, what I claim is 1. In a machine of the character described, the combination with means for centering and supporting one end of a spool and means for embracing the spool near its other end to hold the same against lateral movement, of a plunger movable in the direction of said centering means, a driving-head carried by said plunger, and means for operating the plunger.

2. In a machine of the class described, the combination with means for centering and supporting one end of a spool, of a plunger movable in the direction of said centering means, a driving-head carried by the plunger and provided with an opening in one end, means for embracing the spool at its other end to cause the journal carried thereby to enter the opening in the driving-head when the plunger is caused to descend, and means for operating the plunger.

3. In a machine of the characterdescribed, the combination with means for supporting and centering one end of a spool, of a reciprocatory plunger, a driving-head carried by said plunger and having an opening to receive a journal-pin, and means for actuating the plunger.

4. In a machine of the character described, the combination with a base-frame having an open slot to receive a spool, of a support for one end of a spool arranged in line with said slot, a reciprocatory plunger movable to and from said slot and support, and means for reciprocating the plunger.

7. In a machine of the character described, a base-frame provided with means for embracing a spool to hold the latter against lateral movement, a plunger mounted to reciprocate in guides carried by the frame, a driving-head of the character described carried by the plunger, a bracket located below the plunger and having an opening therein arranged in line with the driving-head, and a centeringpin for a spool removably mounted in said opening in the bracket.

8. In a machine of the character described, the combination with a base-frame having an open slot at its front edge adapted to receive a spool, of a plunger mounted to reciprocate vertically in guides carried by said frame, a U -shaped bracket mounted below said baseframe, centering means for a spool carried by said bracket, a lever for actuating the plunger, and means for operating said lever.

9, In a machine of the character set forth, the combination with a base-frame having an open slot at its front edge adapted to receive a spool, of a plunger mounted to reciprocate in guides on said frame, a driving-head carried by the plunger, a U shaped bracket mounted belowsaid base, a centering-pin for a spool removably mounted in an aperture in said bracket, a lever vfor actuating the plunger, and a foot-treadle having a connection with the lever.

In testimony whereof I affix my signature in presence of two witnesses.
